Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 774, here are decompositions:

  • 5 + 769 = 774
  • 13 + 761 = 774
  • 17 + 757 = 774
  • 23 + 751 = 774
  • 31 + 743 = 774
  • 41 + 733 = 774
  • 47 + 727 = 774
  • 73 + 701 = 774

Showing the first eight; more decompositions exist.
